i know the people trying to get quaternions replaced with geometric algebra pushed that heavily. the way operations are derived are fairly easy to explain in GA, as well as individual steps of wedge operators being something a human can see, whereas when i was faced with trying to reason about quats without math training it was just fucking magic numbers doing formulas.
